Killer Mark Robinson said he was unhappy after his bread quota was changed from two loaves weekly to two to three slices a day.

As he was being taken back to his cell in Wakefield jail from collecting a meal in the “close supervision centre” - which houses some of the country’s most dangerous offenders - 20-stone Robinson told an officer: “I’m not happy with the bread situation boss. I’m not happy and I might kick off”.

Within seconds Robinson, who is over six feet tall, threw his tray up in the air and kicked the officer in the groin so hard it lifted him up off the ground.

Other officers then went to his assistance, including Craig Dudley who was punched in the face with such force it broke his nose.

It took 10 officers to subdue Robinson - including one who suffered a perforated eardrum.

A total of five were treated in hospital.

Robinson originally from Billingham was only 17 when he was first convicted of murdering a 32-year-old married neighbour Patricia Wagner after confronting her at her home.

He served a life sentence, was released and killed again - this time for repeatedly stabbing his girlfriend Sharon Morley, 25.

He was then ordered to serve a whole life tariff.

Robinson, now 52, refused to leave his cell at the jail today to appear on a video link to the crown court and was sentenced to three years in his absence for assault and affray.
